Q: lose shelf power supply

Could someone please explain what happens when you loose a single
power supply in a shelf?

Is the filer smart (dumb) enough to halt?
Do I get 'double disk error' and loose the filesystem?

There is a discussion going on here as to what happens in a hardware RAID
configuration vs a NetApp filer when a power supply fails.

The thought is that if I have only one power supply in a shelf and it
fails (failing 7 disks) it is like having multiple disks fail and
therefore you loose the filesystem.

Thanks,
George
